Packaged in a beautiful black-lacquered wooden storage case, this DVD collection includes the serials The Phantom Empire and Undersea Kingdom.

The Phantom Empire (1935): Hidden deep beneath the earth is the lost civilization of Murania, ruled by the ruthless Queen Tika. When Gene Autry stumbles across the hidden city, the Muranians are determined to silence him and destroy his ranch to protect their secret world. The queen's masked army of thunder riders hunts down the singing cowboy and brings him to their subterranean city. Teeming with futuristic weaponry and machinery, the unfamiliar land resembles an alien planet. It looks like the last round-up for Gene when deadly robots attack him with flamethrowers. Autry's daring and the Queen's bloodlust escalates to a final confrontation which threatens the entire populace of Murania with total war. This 12 chapter cliffhanger produced by Mascot Pictures is the earliest science fiction serial to integrate western themes.

Voyaging deep below the surface in a rocket-fueled submarine, Crash and his nautical crew become entangled in the turbulent forces of Unga Khan, the sinister ruler of Atlantis, who is determined to conquer the world. Crash must contend with brutal, chariot-riding soldiers and the deadly robotic Volkites in his mission to foil Khan's quest for total domination. Lon Chaney Jr. co-stars. Includes all 12 chapters.
